Bichon Frise

Border Collie

Boykin Spaniel

Chesapeake Bay Retriever

Chihuahua

Dachshund

Goldendoodle

Hair Curl (DNA marker tested – KRT71) The presence of “Curl” is inherited as an autosomal Dominant trait. Therefore, dogs having only 1 copy of the curl allele will appear to have a curly coat, but will likely pass on the non-curl allele 50% of the time.

Here are the 3 potential genotypes reported:

R151W -/- (2 copies of this non-hair curl allele)
This dog does not have the coat curl gene

R151W +/- (1 copy of this hair curl allele/1 copy of non-hair curl allele)
This dog will likely pass on the coat curl gene to 50% of its offspring & the non-curl gene to 50% of its offspring

R151W +/+ (2 copies of this hair curl allele)
This dog will pass on the coat curl gene to 100% of its offspring
